2 SHBETSASHBET 2,

t the swinging arm 12, which strikes the stitch .cam 5 passing for this purpose below the dial cap. Therefore, as the arm 12 swings, toward the center of the dial, the arm 2O will strike the stitch cam 5 and move it inwardly at the same time and to the same extent that the Linder' stitch cam is moved, so that the relitivg times of- 'drawing lodps in respect to t-hdftwo and two arrangement of the needles wi "be preserved in making this loose course as n making the regular two and two rib.` y' this invention not only are long loops formed on both the cylinder and dial for the 'loose course, but the thread is not strained, and furthermore the loose course will be i clearly'visible on both sides of the fabric.

The racking' of the dial may be accom Aplished in various ways. We have shown an arm 2 for this purpose which 1s connected with thedial through a dogless arrangenient, like that disclosed in Letters Patent of the United States granted to G. L. Ballard, December 20, 191i, #1,012,966, this arm corresponding to the arm l/.t of said patent, but in the resent invention it is operated automatically by an arm 2.2 on the vertical rock Shaft 23, this rock shaft being operated through suitable connections to a pattern mechanism.

The pattern wheel is shown generally at 24, this being operated by any suitable pattern mechanism common in the Wildman as indicated-in Fig. 1.

type of machines. It has pattern blocks 25 for operating a lever 26 'which raises and lowers the pattern disk l5, said lever being pivoted to the frame at 27, and the pattern Wheel also has pattern blocks 28 for operating connections 29, 30, shown generally in dotted lines in Fig. l for operating the vertical rock shaft 23, from which it will be seen that the control .of the vshogging and the operation of the .loose course attachment takes place automatically and in its best form from the same pattern wheel.

" When the dial is shogged it is revolved "gainst the direction of motion of the. canis.

nsequently, when it is desired to return the dial to its original. position, it is merely released; upon which, the action of the cams through 'the needle butts against the dial turns the latter back to the original position.

The dial stitch cam is returned to normal position by the coil spring'bearing thereon, The cylinder stitch cam is Areturned by the usual coil spring shown in Fig. 2 pressing up against the under side of the cam member 9.

ohperati'ng the stitch cam of the dial, and we y, erefore' place an arm or projection 20 on We claim as our invention 1. In combination with a cylinder and dial 'having their needles arrangedQ-in two and two relation, a cylinder stitch cam, a dial *Stitch cam, said cams being vadjustable substantially in unison for making a loose course, means for adjusting both of said cams when the loose courseis to be made, and means for shogging the dial, substantially as described.

2. In combination in a knitting machine,

a cylinder and dial, stitch cams therefor, means for shogging the dial to a two and two relation, means for shifting the stitch cams in unison for making loose courses in the two and two fabric, including a swinging arm and a projection thereon to contact with and to be retracted away from the dial cam 'as the arm swings to and from the dial, pattern controlled means for operating the shogging means and the stitch cam shifting means, and means for returning the stitch cams to normal position, substantially as described.

8. In combination with a fixed cylinder and dial, a stitch cam for the cylinder and a stitch cam for the dial, a post connected with the cylinder stitch cam having a cam plate on its upper end, a swinging arm carried by the rotary cam box of the cylinder having a portion to engage the cam plate for depress mg the cylinder stitch cam, said arm having a pro]ection to contact with and operate the dial stitch cam when said arm swings toward the axis of the head, and to be retracted away from the dial cam when the arm swings back, tappet arms for operating the swinging arm, and a pattern controlled member for operating the tappet arms, substantially as described.

4. In combination with a cylinder and dial, stitch cams for the cylinder and dial, a member having a back and forth movement toward and from the dial, a post connected with the cylinder stitch cam and operated by said member, and a pin mounted 0n said. member and adjustable longitudinally there' ou to alter the position of its end in relation to the dial stitch cam, said end contacting Lliti substantially as described.

In testimony whereof, we atiix our signatures in presence of two witnesses.
